A hypothetical, neutral → elementary particle
which plays a key role in the → standard model
of → particle physics.
This massive particle, whose mass is estimated to be about
125 GeV (→ giga → electron-volts)
and a zero → spin, carries the
→ Higgs field. In the current version of the
→ electroweak theory,
→ W boson and → Z boson
and all the fundamental constituents
(→ quarks and → leptons)
get their masses by interacting with the Higgs boson.
The Higgs boson is produced by the fusion of two → gluons
via a triangular loop of virtual top quarks. In the decay process, a loop of
virtual top quarks allows the Higgs boson to decay into two photons.
The particle's discovery was announced by → CERN in July 2012.

Named after the Scottish physicist Peter Ware Higgs (1929-), one of the researchers
who theorized the existence of this particle in 1964. In fact three groups of
physicists almost simultaneously published their results on this subject:
François Englert and Robert Brout in August 1964; Peter Higgs in October 1964;
and Gerald Guralnik, Carl Hagen, and Tom Kibble in November 1964;
→ boson.

intermediate boson

Fr.: boson intermédiaire

A hypothetical → elementary particle
that mediates the → weak interaction, carrying its effect
from one particle to another as the photon does for electromagnetic interactions.
First introduced in 1961 by Sheldon Glashow.

A → boson particle that, along with → Z boson,
mediates the → weak force in particle interactions.
Two kinds of W bosons exist, the W+ and its antiparticle W-.
With a mass of 80.4 GeV/c2, the W boson is almost 100 times as massive as the
→ proton.
